Already posted this but want more opinions

My bf is my absolute world and my best friend I really couldn’t imagine my life without him.

he was really the only person I would message on Snapchat until this other boy (gonna call him ‘L’) would always pop up to my snapchat story (my boyfriend and L were literally best friends once and then their friendship group had an argument but they’re still friends just not as close) at first it was just a couple of things being said but now he will pop up to my story and we will talk for hours and I honestly enjoy it but in a friendly way. We literally talk about the types of girls he likes and i tell him he should shoot his shot because he could so get the girls.

But i feel really guilty for wanting to talk to him all the time and liking talking to him it doesn’t feel right but I know my bf talks to other females so then I don’t feel bad but still I was always the type of person to say why do people text other people when they’re in a relationship and I feel like I’ve gone against everything I’ve said.

Also I have dreams about me kissing L and I get upset in the dream because I ruined everything I had and it’s so confusing. L used to be in my dreams all the time and my friend thinks I like him but I really don’t I just like talking to him. But it’s so annoying because i feel like I’m being a bad gf even though my boyfriend is the only boy I’ve ever loved and I think will ever love ughhhhh

I just wanna know can you like talking to someone without liking them
